Curtis, executrix of said David C. Curtis, deceased Application August 13, 1956, Serial N- 603,766 '6 Claims. (or. 12-15 This invention relates broadly to the art of shoe manufacture and in its more specific aspect it relates to apparatus for slip lasting and spotting the heel wedge; and the nature and objects of the invention will be readily recognized and understood by those skilled in the arts to which it relates in the light of the following explanation and detailed description of the accompanying drawings illustrating what I at present believe to be the preferred embodiments or mechanical expressions of my invention from among various other forms, arrangements, combinations and constructions, of which the invention is capable within the spirit and scope thereof.

In the manufacture of shoes after the uppers have been cut and stitched to a sock lining it is necessary to apply the upper and sock lining stitched together to a last. This lasting operation requires the upper to be tightly fitted or applied on the last and it is a prerequisite to a successful slip lasting operation that the seams on the upper and sock lining be positioned properly relative to the last, that is that the seam is properly adjusted about the edge of the shoe. It will be recognized that the lasting procedure if done by hand is a difiicult task, for the upper must be pulled over the last with a tight fit and in addition the seam must be properly adjusted. As a matter. of fact difficulty is experienced by shoe manufacturers in securing and keeping lasting operators because of the difficulties of the hand operation.

Complicated and expensive machines have been devised for performing the lasting operation, such machines often involve pincer arrangements which grasp the upper and pull it over the last. There are certain inherent disadvantages in addition to complexity and cost of the machines of the prior art of which I am aware and the apparatus whichI have evolved and shall describe hereinafter has overcome these disadvantageous characteristics of prior lasting machines.

It has been one of my prime purposes to design an apparatus for lasting which fully eliminates thenecessity for the operator to perform any pulling, stretching or other slow arduous task on the upper in the application thereof to the last. The operator of my slip lasting and platform spotting machine merely loosely slips the last into the unlasted shoe comprising an upper assembled with a sock lining and then initiates and controls the operation of the apparatus which automatically and in a simple manner applies the upper to the last and adjusts the seam relative thereto. Actual tests which I have made under normal operating conditions have established that the lasting apparatus produces a much better shoe in which the proper positioning of the seams is assured. From my experience in the shoe production field I have found that one of the major difficulties in hand lasting is to secure the desired and proper seam positioning.

In evolving this apparatus I have provided means which apply pressures on the upper andsock lining at the bottom and top surfaces thereof which produces forces on the upper which cause it to be properly fitted on and applied to the last with the seams properly positioned relative to the last. The means which I utilize to apply such lasting pressures to the upper and sock lining are under the control of the operator and are adjustable relative to each other and to the last.

The apparatus which I have devised serves a dual function, for it not only operates to apply the assembled upper and sock lining to the last but it also functionsv to spot the heel wedge of the shoe; The apparatus serves in this step of the operation to force the wedge into proper position in alignment with the heel of the shoe and centered in the wedge cover.

The apparatus of this invention is inexpensive to construct and to maintain for it has relatively few working.

parts and no complex. mechanisms are involved. A factor of importance to the apparatus and its success lies in the" fact'that its operation is relatively simple and' highly skilled operators are not necessary for its successful operation.

With the foregoing general objects, features and results and platform spotter apparatus with parts thereof broken away.

In the accompanying drawings I have used the numeral- 1 to designate the supports or legs of my apparatus, sheet material 3 may, if desired, be fixed to the legs to enclose three sides of the apparatus, leaving the rear side 5 open.

apparatus.

I mount the mechanism for performing the slip lasting operation onthe platform 7 in the following manner. An upstanding last jack 9 is fixedly mounted in any suitable manner on a. jack slide plate 11 which ,is-

adapted for horizontal reciprocatory movement relative to the platform 7' in a direction toward and fromthe,

The jack slide plate 11 is pref-'v erably though not necessarily of less length than the front of the apparatus.

width of the platform. A conventional wooden or the like last generally designated by numeral 13 is removably mounted on the last jack 9. I Any suitable arrangement for mountingthe last onzthe jack may be em ployed, such as a pin 15 which projects upwardly from the jack and may be received a socket which is.pro-

vided in the last. It is-tobe observedthat with the last in operative mounted position the toe portion 17 of the last is directed toward the front of the apparatus while the heel portion 19 of the last is directed toward the rear of the apparatus.

A track for mounting and slidably guiding the jack slide plate 11 is mounted on platform 7 and may com- Fig. 7 is aview illustrating the next step of the lasting operation with both rolls operating on the shoe. t

A substantially flat platform or top. 7 is fixedly mounted on and supported by the legs 1 of'the prise bottom strips 21: and top strips 23 spaced apart by narrower intermediate strips 25. Two sets of strips are used, one for supporting and guiding each longitudinal edge of plate 11 as is clearly illustrated particularly.in Fig. 2. ofthe. drawings. Each set of guide, strips may be: bolted or otherwise secured to platform 7 as by bolts 27. It will now be recognized that the plate 11 is slidably supported on and between strips 21 and is slidably maintained in proper position by strips. 23 and 25. Any other suitable arrangement for slidably supporting plate 11 may be resorted to and still fall within the spirit and scope of my invention.

For a purpose to be hereinafter described in detail I fix a rack bar 29 on the under surface of the jack slide plate 11. The jack slide plate is formed with a central longitudinally extending slot 31 therein which extends forwardly from in front of jack 9 to a point spaced from theforward transverse edge of the slide plate. I mount a toe roll supporting standard 33 in this slot for adjustment therealong to position the toe roll standard at different distances from the last jack 9. Any usual means may be used for adjustably mounting the standard on sliding plate 11, for instance the standard may be provided with a stern extending through the slot and flanges on. the stem and a clamp nut 35 having a hand lever 36 threaded on the standard for clamping engagement with the plate 11. It will be recognized that with the toe roll standard 33 fixed in adjusted position on plate 11 it will move therewith and with jack 9 when the plate is moved in its guide tracks across platform 7. The standard 33 may be of sleeve form to telescopically receive therein a stem 37 which carries at its upper end a bearing bracket 39 which mounts therein a toe roller 41 adapted for rotation on a horizontal axis by means to be hereinafter described. The toe roller is preferably formed of a firm rubber. The stem 37 may be adjustably supported in sleeve standard 33 by a set screw or the like 45. Various other mounting arrangements for the standard 33 are within my contemplation and any ex-. pedient which allows for vertical adjustment and horizontal adjustment of the toe roll 41 relative to the sliding plate 11 and jack 9 fall within the scope of my invention.

As will become apparent as this description proceeds the toe roller 41 is adapted to operate on the toe portion of the upper and I provide a further roller 47 of firm rubber which is adapted to operate on the sock lining from the front thereof rearwardly to the heel thereof. Consideration of the drawings clearly illustrates that this top roller is operatively positioned in a plane above the toe roller 41.

The top roller 47 is fixed to its shaft 49 for rotation therewith, the shaft 49 being suitably journaled at each end in vertically slidable panel elements 51 so that the top roller is vertically adjustable relative to the last 13. A pair of upright housings or slidable panel supports designated generally by numerals 53 and 55 are mounted in spaced oppositely disposed relation on platform 7 on each side of jack slide plate 11. Each housing is formed with side walls 57, a vertical plate 59 serving as a guide for panel elements 51 and a top 61. The housing 55 may be provided with a back enclosing wall 63. It will be understood that the vertically slidable panel elements 51 are adapted to be guided in their vertical movements between the side walls, vertical plates and tops of the housings, and that top roller 47 and its shaft 49 extend between the housings and will move vertically corresponding to the vertical translation of the slidable panel elements 51.

'I' provide efficient means under the control of the operator of the apparatus for causing vertical reciprocation of the panels 51 and consequent raising and lowering of the top roller 47. I provide a lever 65 which is pivotally mounted as at 67 to a leg reinforcing member 69 and extends rearwardly therefrom and outside the confines of the apparatus as defined by the legs thereof, the

. lever 65 being provided with a foot treadle or pedal 71.

A link 73 is pivotally connected to lever 65 at 75 and extends upwardly therefrom to a pivotal connection 77 with a transverse element- 79.which at its ends is connected to the lower ends of slidable panels 51. The

pedal, lever and transverse element 79 are biased up;

7 to extend downwardly therefrom and pivotally supports. a pawl 85, theworking nose 87 of which extends throughv an aperture 89 which is provided in the platform 7. The.

pawl is provided with a weight 91 at its .tail end. to cause working nose 87 thereof to normally move upwardly throughthe aperture 89 and intoengagernent with the teeth on the rack bar 29 to thereby lock jack slide plate. 11 in adjusted horizontal position. Iprovide means for. causing pivotal movement of the pawl to releaselit fromv position with the working nose 87 thereof engaged with.

the teeth of the rack bar, such means may comprise. a bumper element 93 which is fixedto .thetransverse member 79 for vertical movement therewith. It'will thus be understood that when the pedal 71 is depressed to move the top roller 47 into downward operative position the transverse member 79 is likewise translated downwardly as is the bumper element 93. In this down posi-. tion the bumper element 93 is out of engagement with the pawl so that under the influence of the weight 91 the nose of the pawl rocks upwardly and is. in engagement with the teeth of the rack bar. When the pedal is released the spring 81 causes upward movement thereof with a corresponding upward movement of the lever 65 and transverse member 79, whereupon the bumper element 93 also is raised and engages the pawl to therebycause pivotal movement thereof to release the working nose from the teeth of the rack bar so that the slide 11 is in unlocked condition and may be adjusted horizontally.

The mechanism which I have just described, and which provides for locking the slide 11 at certain times during the slip lasting process, all as will be explained in detail hereinafter, is one from among many which may be used for locking the slide plate 11 when the pedal 71 is. depressed and it is not my intention that this particular arrangement for actuating the pawl be employed. It is to be understood that when the roller 47 is caused tomove downwardly into operative position the slide plate 11 is automatically locked against horizontal movement in its tracks.

As I have stated hereinabove, the apparatus of thisinvention includes means for causing rotation of the top roller 47. Such means consists of an electric motor 95 which is suitably mounted at any convenient point on or between the legs supporting the apparatus as by bracket 97. The electric motor drives a pulley 99 by suitable means such as flexible belt 101 which extends from the motor pulley to the pulley 99. The pulley 99 is fixed on the lower end of a rotary drive shaft 103 which extends upwardly through the platform 7 and into the housing 55, being journaled in the top 61 thereof as at 105. The rotary drive shaft 103 is provided adjacent to but removed from the top thereof with a worm portion 107 which is in mesh with a gear 109 which is fixed to the extending end 111 of the top roller shaft 49. The plate 59 is slotted as at 110 to permit vertical movements of shaft 111 which extends therethrough. It will therefore be recognized that upon operation of the motor 95 and through the mechanism just described the roller 47 will be caused to rotate, regardless of its vertically ad justed position.

"which is rotatably mounted on a bracket 119.

It is also desirable and necessary to the efiicient and desired operation of my apparatus that the toe roller 41 also be caused to rotate in the same direction as the roller 47, and since it may be also of advantage in the operation of this apparatus to provide means for stopping the rotation of the toe roller 41 at certain steps of the operation, I have provided an arrangement whereby this may be achieved. In order to provide means under the control of the operator of the apparatus for rotating the toe roller when desired, I have extended the rotary drive shaft ofjthe electric motor'95 as at 113 and have fixed thereon a pulley 1-15. I provide a further pulley 117 The pulleys 115 and 117as will be apparent from the'drawings are spaced apart and operate onparallel axes, the pulley 117 being driven by a belt 121 which extends from the pulley 115 to the pulley 117. The drive belt 121 is loosely associated with its two pulleys and is so arranged that unless'it is tightened thepulley 117 will not be caused to rotate upon rotation of the pulley 115; in

effect I have here provided a slip or clutch arrangement.

- I have provided means under the control of the operator for tightening the belt 121 so that the pulley117 will be rotated upon rotation of the pulley 115. This means consists of a lever 123 which is pivotally supported as at 125 to the cross-member 69, the lever 123 extending rearwardly of the apparatus to a point'outside the confines thereof where a treadle 127 is fixed to the end of the lever. Vertically extended link'129 is pivotally fixed to the lever 123 at 130 and extends upwardly from the lever at an oblique angle thereto. At its upper end the link 129 is pivotally connected to a small pulley or roller member 131 which is pivotally connected at its upper end and as at 133 to a further link member 135 which is pivotally connected as at 137 to a bracket 139 which is fixed to and depends from the under surface of the platform 7. The arrangement is such that the roller or pulley member 131 is positioned in the linkage mechanism at a point adjacent to the belt 121. It will now be understood that the operator of the machine may cause the pulley 117 to be rotated, and as will be explained hereinafter to cause rotation of the toe roller 41, by merely depressing the treadle 127 which in turn pulls the link 129 in a downward direction to thereby move the pulley 131 in a more or less lateral direction into tightening engagement with the belt 121 to cause it to cease slipping on the pulleyand thereby produce rotation of the pulley 117.

A vertical shaft 141 is fixed to the pulley 117 and extends upwardly therefrom for rotation therewith and at its upper end is journaled as at 143 to the under side of the platform 7. Adjacent its upper end the vertical shaft fixedly mounts a sprocket wheel 145.

I provide a sprocket chain 147 which extends around the sprocket wheel 145 and from there extends toward the front of the apparatus'where it operatively extends about a further sprocket wheel 149 which is journaled from platform 7 as at 151. Thus, with the motor operating and the pedal 127 depressed to move the roller 131 into belt tightening position the sprocket wheel 145 will be caused to rotate and the runs of chain 147 will be caused to travel about the sprocket wheels 145 and 149.

The sliding plate 11 mounts a housing 153 thereon for horizontal movement therewith, the housing 153 "being mounted adjacent the toe roll standard 33. Positioned within this housing is a vertical disposed shaft 155 which at its lower end extends through the plate 11 and the platform 7 and carries on its lower end a sprocket wheel 157 which is so positioned that its teeth extend into the slots of a run of the chain 147 for operative association therewith. Hence when the chain runs are moving the sprocket wheel 157 will rotate as will the shaft 155. Adjacent its upper end the shaft is formed with a worm portion 159 which' is in mesh with a gear 161 fixed on the end of the shaft of the toe roller 41,

the housing 153 having an opening therein so that the gear 161 may be operatively associated with the worm 159. The worm 159 being of a reverse pitch relative to worm 107 so that rollers 41 and 47 will be caused to rotate in the same direction. x

It will now be recognized that the toe roller 41 will be caused to rotate when the electric motor 95 is operating and the roller 131 is in position tightening the belt 121, which through the mechanism described causes movement of the chain 147 to cause shaft 155 and gear 161 to rotate. I shall describe the actual slip lasting operation wherein the sliding plate is adjustable to various positions relative to top roller47 and wherein the toe roller and its supporting means is individually adjustable on slide 11 relative to the last jack 9. Now it will be under stood that with the arrangement I have provided the toe roller will be rotatable regardless of its adjusted position because sprocket 157 will at all-times be in operative engagement with a run of chain 147 at some point therealong. The toe roller 41 is also adjustable vertically within the standard 33, however the rotation of the roller 41 will not be disturbed by such vertical adjustment because of the fact that gear 161 will at all times be in mesh with some point along the worm 159.

If desired a separate motor may be employed to operate the toe roller, or it may be arrangedfor operative rotation at all times. If found desirable conventional gear reduction means may also be incorporated in the operative train for the toe roller. In this embodiment I have illustrated one example from among many of means which may be successfully used to carry out my highly advantageous slip lasting operation. In the slip lasting operation the operator of the apparatus first inserts the wooden last into the upper 165 by hand. The upper has of course been cut and stitched to a sock lining and is otherwise in. readiness for the slip lasting operation. The insertion of the last is done by hand and is a simple operation and is preferably accomplished with the last 13 removed from the jack 9. When the assembled upper and sock lining has been loosely applied on the last the machine operation is ready to begin and the operator fixes the last on the jack.

This apparatus will of course function for many styles and sizes of shoes requiring corresponding different lasts. When the last with the upper loosely thereon has been fixed on the jack the operator adjusts the vertical position of the toe roll by raising or lowering the stem 37 in the standard 33 and locks it in the desired vertical position by means of the set screw 45. The toe roll is adjusted so that it is in contact with the toe of the upper. The toe roll is then adjusted to the proper horizontal position by loosening clamp nut 35, moving standard 33 in the slot in slide platell and then tightening the clamp nut when the proper position is reached. The motor is then started and the toe roll is driven counter clockwise and the upper roll is driven counter clockwise. Fig. 6 of the drawings illustrates the position of the parts at the initiation of the slip lasting operation with the toe of the upper resting on the toe roll 41. The operator then depresses both pedals 71 and 127 to cause rotation of the toe roller which tends to stretch the toe portion of the upper and urge the upper toward the last bottom and toward the toe end of the last and to provide an excess of material at. the toe which is picked up by the upper roller. The depression of pedal 71 causes the upper roll 47 to be moved downwardly into operative sock lining engaging position as clearly illustrated in Fig. 7 of the drawings. When the upper roll engages the sock lining 165 it pulls the upper back until the seam is stretched over the toe of the last.

When the upper roller is moved downwardly by the operator the slide 11 is automatically locked against horizontal sliding movement by means of the pawl which rocks into position with the nose thereof in locking engagement with the teeth of the rack bar. Thus every time the upper roller is in downward operative position the slide plate 11 is locked against sliding movement. When the seam has been properly stretched as described the operator releases the pedal 71 whereupon the upper roller moves into its uppermost inoperative position and the slide plate 11 is free to be moved since the pawl has dropped into non-locking position. The operator then pushes the jack, last and slide plate forwardly while the toe roll is preferably still rotating holding the seam of the upper in place. The operator then again depresses the pedal 71 to bring the upper roller into downward position in engagement with the sock lining. I This slides the upper further rearwardly down the last as is illustrated in Fig. 8 of the drawings. Fig. 9 of the drawings illustrates the finish of the slip lasting operation with the upper adjusted on the last. Just prior to completion of the slip lasting operation the operator may pull gently on the upper until the heel seam is straight on the last like the toe seam.

The next operation performed by the apparatus is spotting the heel wedge 167. Cement is applied to the insole of the shoe and to the bottom of the wedge. After a short drying period the wedge is placed on the insole by hand. The spotting is done by applying pressure to the breast of the wedge with the upper roll, this action being accomplished of course by depressing pedal 71. Fig. 10 illustrates the first step of the spotting operation. During this action the toe roll need not be rotated so that pedal 127 is released. The operator pushes the last, jack and plate 11 forwardly until the upper roll has forced the wedge back until it is lined up straight with the heel of the shoe and centered in the wedge cover 169. Pedal 71- is then released (see Fig. 11) and the slip lasting and spotting operation are completed.

It will now be understood that I have designed a simple and efficient apparatus for lasting and spotting in the manufacture of shoes, which apparatus eliminates many of the objectionable characteristics which were inherent in prior apparatus.
